Air Conditioner

Abstract: An air conditioner has a refrigeration cycle configured by connecting a compressor a condenser a decompressor and an evaporator. Sealed within the refrigeration cycle is a mixed refrigerant composed primarily of difluoromethane (R32) and tetrafluoropropene (HFO 1234yf or HFO 1234ze) and having an R32 concentration of 70% or less the mixed refrigerant circulates through the refrigeration cycle and the refrigerant condenses when the atmospheric temperature of the refrigeration cycle exceeds 50°C. This allows the discharge temperature of the compressor to be kept equal to that of the currently used R 410A with high efficiency even when the atmospheric temperature is 50°C or greater the reliability of the refrigeration cycle to be improved the warming potential of the refrigerant to be kept low and hence the warming effects to be reduced even when the refrigerant leaks into the atmosphere.
